Specification of Letters Patent.

Patented Nov. 8, 1921.

7 '0 allwhom it may 001mm:

Be it known that I, SAMUEL M. COFFMAN, a citizen of the United States, residing at Kansas City, in the county'of Jackson and State of Missouri, have invented certain new and useful Improvements in Barbers Appliances, of which the following is a specification.

My invention relates to barbers appliances, and my object is to provide a comparatively simple, inexpensive, efiicient, and convenient appliance for supportin hair clippers, massaging and manicuring evices, hair driers, and other devices used by barbers inplying their vocation.

he invention also embodies a support for an electric motor and its attachments for operating the foregoing devices.

The'invention further provides a carriage and an overhead track whereby all of the foregoing may be readily moved from chair to chair of a shop as occasion demands.

Other features and objects of the invention will hereinafter appear, and in order that said invention may be fully understood, reference will now be made to the accompanying drawings, in which:

Figure 1 is an elevation of the complete ap liance ready for use.

ig. 2 is a detail of a suspension rod and parts attached thereto.

ig. 3 is a cross section on line III-III of Fig. 4.

Fig.4 is an enlarged broken vertical section on line IV-IV of Fig. 2

Fig. 5 is a detail, rear elevation of a carriage frame employed in carrying out the invention.

Fig. 6 is a plan view enlarged, of the carriage and a portion of the track thereof.

Fig. 7 is an irregular cross section on line VIIVII of Fig. 6. 1

Fig. 8 is a cross section on line VIII-VIII of Fig. 6.

Fig. 9 is an enlarged, broken, side elevation, partly in section, of a portion of a spider and a switch attached thereto.

F i 10 is, an irregular cross section on line X4; of Fig. 9.

Fig. 11 is a diagram of an electric circuit for the motor and a lamp.

In oarryin out the invention, I employ a wire 1 whic constitutes a track for a carriage 2, adapted to traverse said track and bring the appliance within convenient reach of the various chairs in a barber shop.

The carriage 2 embodies a frame 3 mounted on two peripherally grooved track wheels 4, which are prevented from jumping the track byguard wheels 5. Said guard wheels 5 are slidably and rotatably mounted upon stub shafts 7, projecting laterally from the frame 3 and provided with stops 8 against which the guard wheel hubs are normally held by coil springs 9. On forcing the guard wheels 5 laterally a of the springs 9 gs disclose by dotted lines, Fig. 8, said guard wheels are forced from immediately beneath the track 1, so that the track wheels 4 and the carriage may be lifted fromvsaid track.

11 designates a clamp for locking the carriage at any point upon the track 1. Said clamp is mounted upon a bolt 12, provided at its outer end with a thumb nut 13 and extending through a tubularboss 14 on the back of the carriage frame 3. A coil spring 16 is interposed between the frame 3 and the clamp 11, to push the latter out of frictional engagement with the track 1 when the thumb nut 13 is unscrewed.

The carriage frame 3 is provided with a sleeve 18, split at 19 to render its intermediate portion 20 resilient, so that it may be firmly clamped about a suspension tube 22, through the intermediacy of a stud bolt 23 and a thumb nut 24. By loosening the thumb nut 24, the resilient portion 20 of the sleeve 18 releases its grip upon the suspen-- sion rod 22, so that the same may be adjusted vertically as desired.

The lower end of the suspension rod 22 is provided with a spider 26, embodying a plurality of radially-extending hangers 27 from which the various devices to be use with the appliance may be suspended. Said spider 26 also embodies a'short radial arm 29 in which the rear end of a movable hanger 30 is mounted on a pivot 31. Said movable hanger 30 is provided with a spring detent 32, engaging a plate 33, secured to a switch 34, fixed to the underside of the arm 29. The detent 32 is bent in V-form as indicated at 35, to hold the hanger 30 in the raised or lowered position indicated by the dotted and full lines, respectively, on Fig. 9. The movable hanger 30, carries a contact 37, which is moved into engagement with ainst the action 7 the poles 39 and .40 of the switch 34, when said hanger 30 is raised to the dotted line position. I

One of the hangers 26 has 9. depending hook 42, from which the motor' 43 is removably-suspended by a bail 41. Said motor 43, is provided with a flexible shaft 44, for driving the various devices above-mentioned, a hair clipper 46, being shown attached thereto and suspended from the hanger 30.

Any suitable circuit for. driving the motor 43 and illuminating the lamp '48 supported from a bracket 49 on the suspension rod 22, may be employed. In the diagram, Fig. 11, I have shown the poles of the motor 43 connected to circuit wires 50 and 51, which are removably-connected to circuit wires 53 and 54, respectively, by a two-pole coupling 55. Wire 54 communicates with one pole of the lamp 48 and one poleoof the switch 34, the opposite pole of which is connected to a wire 57 which, together with the wire 53, leads to a plug 59 adapted to be screwed into a lamp socket or otherwise connected to a supply circuit 60, The opposite pole of the lamp 48 connects with the wire 53, through a wire 62.

In practice, the track 1 is hung overhead adjacent a row of chairs and the carriage 2 is mounted on said track, so that it'may be moved along thereon to bring the appliance within convenient .reach of any chair. After the carriage has been moved to the desired point, it is locked from accidental movement through the intermediacy of the clamp 11, and the plug 59, is screwed into any convenient lamp socket. Any one of the devices supported by the spider may then be coupled to the flexible shaft 44. If

the desired device happens to be upon the movable hanger 30, an upward movement of the device as it is removed from said hanger, swings the latter upwardly to the dotted position, Fig. 9, and causes it to close the switch 34. Closing of said switch 34 closes the electric circuit through the lamp 48 and the motor 43, which latter drives the flexible shaft 44. When the barber is through with the device, he hangs it upon the movable hanger 30, which is drawn downwardly by a slight pull upon the device when the same is hung up. As the hanger 30 moves d0wnwardly it opens the switch 34 and thus interrupts the circuit through the lamp 48 and the motor 43. The lamp 48 is so disposed upon the suspension tube 22 as to cast its rays upon the head or face of the customer and thus furnishes sufficient light to enable the barber to perform the operation of trimming the hair or shaving the face.

In large shops having two rows of chairs,

I one on each side of the shop, a track may be suspended adjacent each row, in which case the carriage and parts suspended therefrom may be transferred from one track to the other as occasion requires. The operation of removing the carriage or lacing it on a track be1n facilitated by shifting the guard wheels 5 literally from beneath the track, so that the wheels 4 may be readily lifted therefrom. Should the motor requirrepairs it-may be lifted from the hook 42 without disturbing the rest of the appliance.

From the foregoing description, it is apparent that I have produced an appliance embodying the advantages above enumerated, and while I have shown and described the preferred form of apparatus I reserve the right to make such changes in the constructlon, proportion, and arrangement of parts as properly fall within the spirit and scope of the claims.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is:
